METHOD 0F OPERATING STOP-COCKS.

Specification of Letters Patent No.

To all whom 'it may concern:

Be it known that I, DANIEL N. DUNZACK, of Saleni, in the county of Essexand State of Massachusetts, have invented a new and Improved Lever forTurning Faucets in Pipes, so that They May be Conveniently Operated; andI do hereby declare that the following is a full and exact description.

My invention consists in a lever B, as seen at Figure l, and is forinedin two parts thatit may be lengthened or shortened, as the ease inayrequire, and is fastened together with clasps, Fig. l, and is keptelevated by a screw K, which passes through one of the parts into theother and is behind weight G, and near its top and must be turned backbefore the parts can be separated.

At the top of lever B, is a hollow transverse head A, Fig. l. At thelower end of lever B, is secured a beveled cog wheel P, which intersectswith a larger beveled cog wheel F, there is a forked coupling I, Fig. 4,the square shank of which passes up through cog F. The forks connect cogF with the handle of faucet L, which passes through pipe N, Fig. l. Thenlever B, is turned to the right or left side of pipe N, the cogs P, andF, turn the 'faucet L, and let the water on or off freni the small pipeN, Fig. l.

In the hollow of head A, Fig. 1, there is a slide O, Fig. 2, which titsloosely in said head A, and when lever B, is canted from its center, theslide C, Fig. 2, will pass down tothe lowest end of said head A.

There is a toggle Y, Fig. 3, which passes through slide O, which has anotch and a hole in it for that purpose. Toggle Y, has a base whichcorresponds with the notch cut in slide C. Head A, is provided with twoianges T, T, at the top, upon the inside. Slide C, passes under theflanges, T, T, the top part of toggle Y, passes through slide O, upbetween the two flanges T, T, sufficiently far enough to adinit a stringor wire being attached to it, and slides on the bottoni of the hollow inhead A. There is a pin I at each end of head A, which prevents slide C,freni dropping out of the ends of head A. There is a weight G, the useof which will presently be explained.

The inode of operation is as follows, when the water is to be let intothe sniall pipe 26,975, dated January 31, 1860.

from the inain one X, lever B, being canted to the right side and slideO, being at its lower end, one end of the wire is passed through apulley secured directly over the faucet in the small pipe and fastenedto the outer end of toggle Y, which is in the head of A, Fig. l. Theother end of the string may be carried to any part of the house. Thenthe wire is pulled, the upper end of toggle Y, will be canted toward thewire, consequently its base, which rest on the bottoin of the hollow ofhead A, will lift one end of slide O, and cause it to pinch against thetwo flanges T, T, which will prevent its slipping toward the wire, atthe same time shaft G, will cause lever B, to move in a. prescribedcircle, and in this inanner lever B, is drawn up by the wire or stringbeyond its center, and that part of lever B, whichv has the weightattached to it, having been previously sutliciently elevated, tooverconie the power required to turn the faucet, weight G, will carrylever B, down upon the opposite side from which it started, and when thewire is slacked, slide O, will pass down to the lower end of head A, andis again ready for drawing the lever to the other side. In this way thefaucet in the cellar may be turned to let the water into the small pipe,or let it out through the waste which will prevent its freezing, in thepipe, or having the water injured by its long standing in the lead, withas inuch facility as it can by the faucet in the sink, without thenecessity of going into the cellar in order to turn it. Lever B, isfastened to the niain pipe X with a clasp V, which is tightened with awedge Z that it may be turned to any angle that niay be required toconnect it with the handles of the sinall pipes, substantially as hereinshown and described.

I do not clailn either of the devices separately considered` but lVhat Iclaiin and desire to secure by Letters Patent is The arrangement andcombination of lthe several parts when arranged and combined as hereindescribed, for the purposes set forth.
